IMO Microsoft did an excellent job. Sony's conference was slightly underwhelming. Quantity over quality. They should've skipped all of the shit about the PS4 camera and the TV apps.

Sony's gave me a lot more hype. But they have the games I want and Halo does nothing for me, so opinions. I'd say if Xbox fans are happy with their conference, and PS fans are happy with theirs, then gamers won. Leave the rest to the fanboys.
